so went to r and r the plugs and wires today on my son's car. first plug....would not come out. used considerable force to try to get with a 3/8 ratchet. pb or wd not going to help here. have no idea who put them in last, what kind they are or if anti-seize was used. so trying to determine next move. reluctant to get the car warmed up and then try but not sure what else might work at this point. if they are autolites with no anti-seize, this could be bad.
